A projectile is projected from the origin with a velocity of 35m/s at an angle of 33 degrees above the horizontal. What is the range of the projectile? (Answer in Meter)

A baseball with mass of 0.14 kg is batted into the air. It's initial speed is 38.1 m/s directed at an angle 26 degrees above the horizontal. Of the height of the ball when it was struck by the bat is 35 cm how high off the ground is the ball when it reaches the highest point in its trajectory?

During a tennis match, a player serves the ball at 28.3 m/s, with the center of the ball leaving the racquet horizontally 2.57 m above the court surface. The net is 12.0 m away and 0.900 m high. When the ball reaches the net, (a) what is the distance between the center of the ball and the top of the net? (b) Suppose that, instead, the ball is served as before but now it leaves the racquet at 5.00° below the horizontal. When the ball reaches the net, what now is the distance between the center of the ball and the top of the net? Enter a positive number if the ball clears the net. If the ball does not clear the net, your answer should be a negative number. Use g=9.81 m/s². (a) Number (b) Number Units Units
